Description
1. Self-aligning Capability: Features front-mounted X-type (45°×45°) arc raceway groove design with automatic alignment compensation. The internal mechanism absorbs minor mounting surface deviations to maintain high-precision, smooth, and stable linear motion.
2. High Rigidity Four-Directional Equal Load Design: Incorporates 4-row ball circuits with 45° contact angle configuration, achieving optimal two-point contact for bidirectional radial/lateral load capacity. Optional preload application enhances system rigidity when required.
3. Interchangeability: Stringent manufacturing precision ensures dimensional consistency within stable tolerances. Integrated retainer design prevents ball dislodgement, enabling between and matching guideways while preserving operational smoothness, preload integrity, and motion accuracy.
Category: Linear Guides | Brand: AIRTAC | Series: LSH
Installation note:
Use 4.9-6.9N·m torque for M6 mounting screws. Maintain 0.02mm/m straightness tolerance during rail alignment.
Lubricate with ISO VG32-68 grease through 4 built-in nipples (2 per carriage side).
